Problems solved by technology

Among them, meeting the two requirements of "the distribution coefficients are greater than the standard 130" and "active iodine titration near the end point plus starch indicator solution all show blue and can be titrated to colorless" has become the main problem in the development and production of this type of product. The production formula process can only meet one of the requirements, so it is urgent to invent a compound iodine solution that can meet the standard requirements of the "Compound Iodine Solution (for Aquatic Products)" in the 2017 edition of the "Chinese Veterinary Pharmacopoeia" and can be applied to large-scale production. Iodine solution and its preparation method

Abstract

The invention discloses a composite iodine disinfectant for aquaculture. The composite iodine disinfectant is prepared by mixing the following raw materials in percentage by mass: 1.93 to 2.0 percent of elemental iodine, 1.0 to 1.5 percent of potassium iodide, 10 to 15 percent of propylene glycol, 23 to 30 percent of a thickening agent, 22 to 33 percent of a surfactant, 18.7 to 21.2 percent of concentrated phosphoric acid, 1 to 5 percent of concentrated hydrochloric acid and the balance of purified water. The invention also relates to a preparation method of the composite iodine disinfectant. All indexes of the prepared composite iodine disinfectant meet the standards of a composite iodine solution (for aquatic products) in a chemical roll of Chinese Veterinary Pharmacopoeia 2017 edition, the effective iodine content is stable, the stability is excellent, in addition, the preparation process is simple, production conditions are convenient to control, special production equipment is not needed, the production period is short, the production cost is low, economic benefits are good, and the composite iodine disinfectant and the preparation method are suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound iodine disinfectant solution for aquaculture and a preparation method thereof. Background technique [0002] The compound iodine solution used in the field of aquaculture belongs to the elemental iodine disinfectant. Iodine has a strong bactericidal effect and can kill bacterial spores, fungi, viruses and protozoa. Iodine is mainly present as a molecule (I 2 ) form to play a bactericidal effect, the principle is mainly to iodide and oxidize the active groups of bacterial proteins, such as amino (N-H), hydroxyl (O-H), sulfhydryl (S-H), etc., resulting in protein denaturation and inhibition of bacterial metabolic enzymes system. When preparing iodine solution, an appropriate amount of potassium iodide is often added to increase the solubility of iodine in water. The bactericidal component in iodine aqueous solution is elemental iodine (I 2 ), the ion...
